Error description

• ABEND DUMP TITLE:
  "DB9G,ABND=0C1-00000001,U=SYSOPR  ,M=(N),C=910.IPC
   -DSNYASCP,M=DSNYECTE,PSW=070C1000B33D9DA2,A=0039"
  .
  Causing DB2 to come down.  An overlayed control block in MMIB
  caused this abends0c1 to occur.
  OMPE was doing a freemain storage that saved the pointer to MMIB
  but we didn't update the MMIB hence to abend.
  
  1.) Issuing the command /F O2CI,F EVENTMGR,STOP DB2=<ssid>
  causes a 0C1/RC1 during Object Analysis shutdown. Furthermore
  Object Analysis is shut down for ALL subsystems on the LPAR that
  are configured to use Object Analysis
  2.) In certain situations not all Object Analysis instances are
  started when configured using the autostart option.
  See PK48971 for V310
  .
  KO2E3066S RC=1001
  This problem can occur when OM DB2PE is cancelled while Object
  Analysis is still running. When OM DBPE gets cancelled, it often
  isn't able to clean up the 'hook' it has set in DB2 for Object
  Analysis.  When it tries to install its hook at a subsequent
  startup, it finds that it's place is 'already taken', in this
  case a leftover of a previous run.
  FYI.
  Start O2CI:

Local fix

• 0C1:
  Disable Object Analysis will reduce risk of abend.
  KO2E3066S RC=1001:
  Recycling DB2 or an IPL will solve this problem if it was caused
  when.  To avoid this in the future, make sure Object Analysis is
  stopped before cancelling OM DBPE.

  PROBLEM SUMMARY:
  Changed code to issue FREEMAIN of Object Analysis common work
  areas on subsequent Event Manager start up or OMPE server start
  up.
  
  PROBLEM CONCLUSION:
  Common Object Analysis work areas that interface with the
  target DB2 will only be freed when DB2 is recycled.
  

Problem conclusion

• Common Object Analysis work areas that interface with the
